I have been fighting this thing since i got it put in the ca it hasnt been right since day one! its been 3 years mostly due to the military moving me around, but ive never gotten to really drive my car and its really starting to get to me. Now that my rant is done, i am trying to fix the car wanting to run rich when i hit the gas. it will idle around 15:1 jumping around erratically but when i hit the gas even under no load it goes full rich. ive checked vacuum lines 100 times i hooked up an air compressor and found a few leaks in my intercooler piping yesterday and fixed those. ive put 3 diff MAFS on the car with no help, ive set fuel pressure the correct way, ive set tps, ive set timing. IDK WHAT THIS THINGS PROBLEM IS?!?!? i am running nistune, 444cc inj, n60 or n62 MAFS i have both, nismo adj FPR, gt28rs, FMIC, Greddy type S, CP forged pistons, fully rebuilt with all nissan gaskets 2000 miles ago, AEM UEGO wideband, knock sensor bypassed. Thats all i can think of at the moment. I really want to figure this thing out if not im gonna use the engine for target practice im getting fed up with it and go SR. it will hesistae so bad i can barely drive it. i pulled injectors the other day to look at them but had to sttop mid way and put them back in could my o-ring have started leaking air into the manifold? or do i have a leaky injector ( i wouldnt think bc the idle is on the leaner side) ANYONE give me what ever you have flaming or not i dont care at this point i just want it fixed.:gaah:
OMGWTF
I'd try dumping that gas and run e85 if you have it there, OR install smaller injectors-->not stock, but maybe 370's. Umm, can you tell if your fuel press. stays close to the same when you can it? when you turn just the key on without the eng., does the fuel pump slow and stop after a few seconds? I'm just chiming in. Sorry, didn't see it was a ca18, but it still applys.
Sounds to me like there's something hinky with your injectors or your tune. Might have to send in your ecu.
Those 800's sound big for that, but if your ecu is tuned specific for 800's, then it all might work right. I get your frustration, tho, if it doesn't work still, you'll have to bite the bullit and drag it to a tune shop. IMO. Keep us posted.
finally had a breakthrough with this i think. i called up autovaughn performance and they put me in the right direction. since i am running the ca18de computer i need to run the ca18de maps then tune that to run the turbo motor fuel and timing maps. so far it seems to be much much better i have to change my plugs bc i have a sputter under cruise but i think this may have solved my issues. and nistune is accounting for the 800cc injectors just had to do a bit of tweaking to get it to act right
this isn't like an old automated musclecar that runs solely off a bunch of good parts and components.
the computer plays the biggest role. make sure its tuned WITH each upgrade. its programed to run a certain way at given situations and it won't adjust itself when u put new things on your car. you need to go in and do this.
